There is no evidence that scientific understanding replaces religious belief in modern cultures. America has become more religious over the course of its history, not less, despite the influence of science and engineering…. A very high proportion of scientists themselves profess a belief in God and participate in organized religions…. Clearly, we must think of religious thought as something that coexists with scientific thought, not as an inferior version of it.
